TIRE-SECURING MECHANISM.

To all whom it may concern:

Be it known that I, LUTHER L. Greece, Jr., a citizen of the UnitedStates, residing at Lonejack, in the county of Jackson and State ofMissouri, have invented certain new and useful Improvements in Tire-Securing-Mechanisms, of which the following is a specification.

My invention relates to improvements in tire securing mechanisms.

The object of may invention is to provide a reliable, simple and durablemecha nism for releasably securing tires of vehicles to rims of theclencher type.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawings which illustrate one form of my invention,Figure 1 is a side View partly broken away of a tire and rim securedtogether with my improved securing mechanism. Figs. 2 and 3 are sideviews of the two rings respectively which fit into the grooves of theclencher rim. Fig. 1 is an enlarged cross section View. Fig. 5 is a sideview of a part of what is shown in Fig. 4:. Fig. 6 is a vertical sectionon the line ab of Fig. 7. In this view the locking member is shown indotted lines in the position which permits the removal of the tiremember. Fig. 8 is a View partly in side elevation and partly broken awayof the crank mechanism for adjusting the bolts or screws which actuatethe locking members. Fig. 9 is an end view of what is shown in Fig. 8.

Similar reference characters designate similar parts. I

1 designates an annular tire member which may be ofany suitable form,and which is shown as being of channel form in the drawing.

2 and 3 designate respectively two rings which are adapted to be mountedrespectively in the two grooves of a rim 4 of theclencher type. The tiremember 1 encircles the rings 2 and 3 by which the tire member issupported. The inner periphery of the tire member 1 is provided with aprojection 5, preferably of annular form,

and which engages the inner side of the ring 3. The ring 2 has on itsinner side an annular groove 6 which is adapted to receive the outwardlyturned projections 7 of a plurality of radial locking members 8, whichextend respectively through slots 9 provided in the tire member 1. Thelocking members 8 are provided with transverse screw threaded holes inwhich are respectively fitted transverse screws or bolts 10, which arerespectively rotatively mounted in casings 11, which are pivotallymounted in housings 12 respectively. The housings 12 are secured to theouter periphery of the transverse portion of the tire member 1 and covertheslots 9. The screws 10 are provided each with an axial trunnion 18,which extends through the inner end of the casing and housing adjacentthereto. By turning the screws 10, the locking members 8 may be movedtransversely of the tire member 1 in the slots 9 to and from positionsin which the projections 7 will be in the annular groove 6. Each slot 9is provided, as best shown in Fig. 6 and Fig. 7, with a lateral portion14 through which the adjacent locking member 8 may be swung to theposition shown in dotted lines in Figs. 6 and 7, when it is desired todetach the tire member from the rim, or when it is desired to mount thetire member on the rim. The casings 11 have longitudinal slots 15through which the locking members 8 extend and in which the said lockingmembers are respectively slidable transversely to the tire member.

One side of the tire member 1 is provided with a plurality of holes 16which are disposed opposite respectively to the screws 10, and which areadapted to receive the hexagonal portion 17 of awrench 18 in which isrotatively mounted another crank wrench 19 having a socket 20 adapted toreceive the square heads of the screws 10. The wrench 18 has mounted in.it a screw 21 which projects into a peripheral annular groove 22 in thewrench 19, thus permitting rotation of the wrench 19 in the wrench 18.The outer end of each casing 11 on its inner side is of hexagonal shapeand fitted to the portion 17 of the wrench 18.

The rings 2 and 3 are composed each of two semicircular members whichare de tachable from each other so as to permit of.

of the slots 9, after which the wrench 18 is turned so as to swing thecasings 11 and screws 10 to the dotted position shown in Fig. 6. Thetire 'member 1 may then be slipped over the rings 2 and 3 which havebeen mounted in the rim 4. The annular flange projection 5 will strikethe inner side of the ring 3, thus limiting the movement of the tiremember in that direction. The wrenches 18 and 19 are then appliedsuccessively to the casings 11 and screws 10, the casings 11 beingturned with the locking members 8 to the position shown in solid linesin Fig. 6. The wrench 19 is then turned so as to move the lockingmembers endwise on the screws 10 to the position shown in Fig. 7, inwhich position the projections 7 will enter the groove 6 in the ring 2,thereby locking the locking members 8 to the ring 2.

I do not limit my invention to thestructure shown and described as manymodifications, within the scope of the appended claims, may be madewithout departing from the spirit of my invention.

Having thus described my invention, what I claim and desire to securebyLetters Patent, is:

. 1. In tire securing mechanisms, a ring adapted to be mounted inagroove of a clencher rim, an annular tire member encircling the ringand having a slot, securing means adapted to be mounted in the othergroove of the clencher rim and against which the tire member bears, alockingmember extending through the slot and having means for lockinglyengaging with the'ring, and a screw rotatively mounted on the tiremember and having threaded engagement with the locking member for movingthe locking member laterally to and from the locking position. a

2. In tire securing mechanisms, a. ring adapted to be mounted in agroove of a clencher rim, an annular tire member encircling the ring andhaving a slot, securmg means adapted to bemounted in the other groove ofthe clencher rim and against which the tire member bears, a housing onthetire member over the slot, a casing. ro-

tatively mounted in'the housing. and having a longitudinal slot adaptedto register with the slot in the tire member, a locking member slidablein the slot of the casing and movable therewith to and from'a positionin which it will extend through the slot in the tire member, and movablein the slot in the tire member into and out of locking engagement withthe ring, and a screw rotatively mounted in the casing and having athreadedengagement with the locking member for moving the locking memberto and from the locking posit-ion.
